That's most likely due to

https://github.com/pgf-tikz/pgf/issues/1062
https://github.com/pgf-tikz/pgf/pull/1073

but this MWE

\catcode`\@=11

\begingroup
  \lccode`\~=`\"
  \lowercase{\endgroup
    \def\pgfmath at catcodes{%
      \catcode`\==12 %
      \catcode`\,=12 %
      \catcode`\|=12 %
      \catcode`\&=12 %
      \let~\pgfmath at char@quote
    }}%

{\pgfmath at catcodes "}

\bye

works in Knuth TeX, so it's likely not our fault.

Henri
